Was there a reason, you had a mold testing done? I would have thought, you would see it in the basement, if you just finished remodeling it. I might want another test done by another company and see if you get the same results. Are you smelling it, in your house? If you have mold anywhere, you will smell it, especially in the areas, that have it.

We are in Indiana so the summers are warm / humid but not year round. We did have a problem with two of the gutters when we moved in about a 1.5 years ago - they were routed underground and started backing up so we had a company come out and re-route them with pvc and guards - no problem since. We have an industrial strength dehumidifier in the basement but there is a giant crawl space - about 750 square feet - my husband crawled around down there and didn't see anything, but who knows...maybe a professional would see something we don't.

This is a 1970s home so I don't know about the waterproofing on the outside of the basement...it's probably 2500 square feet around the outside of the first story footprint so not insignificant if that involves having it dug around. But when we renovated the basement - pulled off paneling and put up framing, insulation, and drywall - we painted drylok as instructed on the concrete blocks before framing. We did see evidence of water damage on some of the paneling, but it was in the same place where the gutters had backed up. We left everything off the walls for a few months in the spring just to make sure there wasn't still an issue. Never saw mold (again - we're not professionals so if it wasn't obvious - like the typical black or fuzzy stuff - we may have missed it).

I appreciate all of the feedback...all of the renovations are about 2x what we ever thought (mainly because of things like the underground routing, having to replace all of the plumbing, some windows failing - the boring stuff that's also necessary) so we want to do what's right with this mold situation but also not break the bank. The reason we initially had it tested was some new allergies when we moved in and high cholesterol (otherwise healthy without a history and we are nutritionally conscious - both of us tested high a year after living here - prior year was not high - , and that can be the body's response to mold).

For reference, the testing in the basement has an ERMI result of 22.6 (anything over 20 is high and the report says "re-occupancy is ill-advised until futher remediation and re-assessment are conclusive"). Sounds scary - not like we can move out until we figure it out. The Group 1 - Water Damage Molds were a sum of 35.2, and the highest (100 fold higher than normal) were Aspergillus sclerotiorum, aspergillus versicolor, eurotium (asp.) amstelodami, and penicillium corylophilum.

You would most certainly know if you had active mold. Its not easy to miss, and your nose would tell you too. It smells, and its not a good smell. I would however, have someone check out the crawl space, since you obviously do have some moisture coming from there. There should be heavy duty plastic on the ground in there, and may be other things, that should be done too. Since you are living there, you may not smell some things anymore, because you are used to them. Invite a friend, over and ask them to smell around and see if they smell any mold. Someone you trust, to give you an honest answer.
